I am running the ID1000 injectors with my Motec on trail at 290-300HP and absolutely love them. No low speed or idle quality problems, have been very consistent since I figured out my fuel pump supply gremlins.

I have the same question for my 600cc injectors on a 2006 Apex engine.
They replace the Stock injectors.
I do not have external injectors inside the IC.
I'm running a GT2871 turbo with .64 AR exhaust.
I had problems With flooding the engine killing spart plugs.
I Guess I did not remove enough fuel in my RB3 when changing from Stock to 600cc injectors.
Going to change out the RB3 to a PCV when my engine is rebuilt.
Anyone having a PCV fuel map for 350 to 400 HP to share?
Building a map from scratch is a lot of work without a dyno, any help is appreciated.

I use gen 5 mcx and megatune. I assume I can use that with bigger injectors. I have the oem injectors and have turned the fuel pressure to 70psi to give it some more fuel, to be able to run more boost. With bigger injectors will it be better to turn down the pressure or to keep a high pressure and adjust the mapping

Great tool to see what size injector you need. 725's will be out of fuel at 400 ish hp with 43.5 static fuel pressure. We prefer to keep the fuel pressure down to 43 base as the higher you set it the harder the pump and electrical system has to work. I would go with ID 850's or 1000's if you think your going to run more power down the rode. 850's with get you to 450 hp at 85% duty cycle 43 base pressure at .60 BSFC. Your going to have to adjust your mapping regardless.

Thanks , very nice page
I'm running the id1000 also
I have run 23lbs with 565cc and 28 with 750cc with a 1 to 1 regulator and base fuel pressure at 43 psi. I do have 565 and 750cc injectors for sale that are direct replacement plug and play if your interested?

I assume there is a difference in quality and way they work. What brand-name and price are you thinking for the 750cc
